Seiko’s Kinetic watches have always been stunning and the sophisticated Premier collection has everything in excess. But you need to move to keep it moving. The rest are taken care of by the time auto-relay system and the auto-initiate power-reserve mode. But even when asleep, it counts the dates, months and years accurately; that’s done by the built-in IC and synched with auto time relay once the watch is reactivated.
Note: The Kinetic is an analog-quartz watch that gets its power from an automatic-generating-system via the Kinetic-Electricity-Storage-Unit, unlike conventional quartz movements fed with button-type batteries.
 

Features:

Perpetual Calendar with leap year correct until February 28, 2100. Time relay system preserves accurate time for up to 4 years. When the watch senses 24 hours of inactivity, it puts itself into suspended animation (sleep mode) to conserve energy. The date continues to advance correctly while the watch is asleep. Wake it up with a few shakes of your wrist and it automatically resets itself to the correct time even if it has been asleep for up to 4 Years.
